Question

10 1000 C) The sides of a rectangle are in ratio 3:2.If it's perimeter is 140 cm then find its dimensions.​

Answer 1

Answer:

dimensions are 42 cm and 26cm

Step-by-step explanation:

let ratio be 3x cm and 2x cm

dimensions become 3x cm and 2x cm

perimeter =140cm

2(3x+2x)=140

2(5x)=140

10x=140

x=140/10=14

therefore dimensions are 3x=3×14=42cm

2x=2×14=28cm
